Amoebas are unicellular. The single cell splits in half to form two new cells. A student claims amoebas are alive. Is the student correct?(1 point)
Responses
The student is correct; amoebas are alive because they become multicellular.
The student is correct; amoebas are alive because they become multicellular.
The student is not correct; amoebas are not alive because they are only made of one cell.
The student is not correct; amoebas are not alive because they are only made of one cell.
The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.
The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.
The student is not correct; amoebas are not alive because two different amoebas are not contributing together to make a new offspring.

The correct answer is:
- cell theory describes the process of how cells come from preexisting cells.
To answer this question, we need to understand what cell theory is. Cell theory is a scientific theory that describes the fundamental properties and functions of cells. It is based on three main principles:
1. All living organisms are composed of cells: This means that every living thing, from the smallest bacteria to the largest tree, is made up of cells.
2. Cells are the basic units of structure and function in living organisms: This principle states that cells are the smallest independent units that carry out all the functions necessary for life.
3. Cells arise from preexisting cells: According to this principle, cells do not spontaneously generate, but instead, new cells are formed by the division of preexisting cells.
Now let's look at the response options:
1. "Cell theory describes the tiny structures that are found within cells." This option does not accurately describe cell theory; it focuses on structures within cells rather than the broader principles.
2. "Cell theory describes the three criteria for determining living things." This option is incorrect because cell theory does not define criteria for determining living things. Instead, it focuses on the properties and functions of cells.
3. "Cell theory describes the process of how cells come from preexisting cells." This option correctly describes one of the main principles of cell theory. It states that cells come from preexisting cells through a process called cell division.
4. "Cell theory describes the difference between multicellular and unicellular organisms." This option is incorrect because cell theory does not specifically focus on the differences between multicellular and unicellular organisms.
Therefore, the correct answer is: cell theory describes the process of how cells come from preexisting cells.
